Description

Technical Field

[0001] The invention relates to the technical field of switching power supplies, and in particular to a modular heat dissipation rectifier switching power supply. Background Art

[0002] A switching power supply is a current conversion device that uses semiconductor power devices as switching elements, adopts a closed-loop control mode, has an automatic protection function, and realizes the transformation of power supply forms. Its main feature is that the main circuit works in a switching state and the switching frequency is high.

[0003] However, during the use of the switching power supply, a filter for eliminating circuit harmonics will be installed inside it to ensure that the switching power supply can operate normally without interference. However, heat will be generated during the operation of the filter, and the switching power supply cannot dissipate heat for the filter in a targeted manner during the heat dissipation process. Therefore, long-term use will cause the temperature of the filter to rise, thereby affecting the elimination of harmonics and affecting the operation of the switching power supply.

[0004] In this regard, the invention with application number CN202311469261.3 discloses a high-frequency synchronous rectification switching power supply and a method of using the same, including a switching power supply body, and also including a filter installed inside the switching power supply body; and a cooling mechanism for cooling the filter, including a cardboard with a C-shaped structure clamped on the surface of the filter, the interior of the cardboard is symmetrically provided with a cavity connected to the outside, and a cleaning member is provided inside the cavity, a metal plate is clamped on the opposite surface of the cardboard, a heat conductive sheet is fixedly installed on the side of the cardboard in contact with the filter, and the drive controller is electrically connected to a semiconductor cooling sheet. Through the coordinated use of various components, the switching power supply body can specifically cool the filter when working, and can intermittently clean the dust adsorbed on the surface of the metal plate to ensure that the harmonics generated inside the switching power supply body can be eliminated.

[0005] In the above scheme, the filter is cooled by using a heat conductive sheet and a semiconductor cooling sheet. There is uncertainty when cooling by the above scheme. Since the heat generated by the filter is determined by the power consumption, the heat generated is different for different power consumptions.

[0050] When the filter 15 of the switching power supply needs to be cooled, the second thermally conductive copper sheet 18 of the water-cooled head 19 is first embedded in the positioning groove on the surface of the first thermally conductive copper sheet 17, so that the first thermally conductive copper sheet 17 and the second thermally conductive copper sheet 18 are in surface contact, and the heat of the filter 15 can be transmitted to the water-cooled head 19; the radiator structure 21 is installed in the lower shell 12, and the radiator joint is connected to the water-cooled head 19 through the first joint 25 and the second joint 26. The liquid in the water-cooled head 19 is passed into the aluminum fins 23 in the installation box 22 for heat dissipation, thereby realizing water-cooled heat dissipation. Compared with the original air-cooled solution, the water-cooled solution of the present invention has a more obvious heat dissipation effect.

After the cold row structure 21 is installed in the lower shell 12, the first cooling fan 27 is coaxially aligned with the heat dissipation tube 3 of the upper shell 11. The heat of the cold row structure 21 can be discharged outwardly through the first cooling fan 27 and discharged through the heat dissipation tube 3 with the top cooling hole 37, thereby preventing heat from accumulating in the power supply body 1 and further improving the heat dissipation effect.

[0054] In addition, the lower shell 12 is formed with an installation opening 50 for sliding installation of the cold row structure 21, and a wind control component 4 for adjusting the height of the first cooling fan 27 is arranged in the power cavity 13. The wind control component 4 includes a lifting plate 49 that can move in the vertical direction of the power cavity 13, and the lifting plate 49 is connected to the first cooling fan 27; when the heat generation of the filter 15 increases sharply, the heat of the first cooling fan 27 cannot be discharged in time through the top heat dissipation holes 37 of the heat dissipation tube 3, at this time, the first cooling fan 27 can be driven to rise by the lifting plate 49 of the wind control component 4, and the heat dissipation tube 3 connected to the first cooling fan 27 rises along the circular groove 31, and the side heat dissipation holes 38 formed on the side wall of the heat dissipation tube 3 rise to expose outward, and at this time, the number of holes for heat discharge is increased; the heat accumulated in the cold row structure 21 is discharged outward through the top heat dissipation holes 37 and the side heat dissipation holes 38 of the heat dissipation tube 3 at the same time, so as to realize multi-directional heat dissipation and further ensure the normal operation of the filter 15 in the power supply body 1; different heat dissipation working modes can also be enabled according to the heat generation to improve the heat dissipation efficiency.

[0055] Preferably, the number of the first cooling fans 27 is two, the number of the circular grooves 31 is two, the two first cooling fans 27 are coaxially aligned with the two circular grooves 31 of the upper shell, a protective net 34 is installed on the top of the first cooling fan 27, a connecting iron plate 35 is formed in the middle of the protective net 34, and a plurality of protruding connecting sleeves 36 are formed on the connecting iron plate 35; the cooling tube 3 is provided with a top connecting hole 32 coaxially aligned with the connecting sleeve 36, and a connecting bolt is installed between the top connecting hole 32 and the connecting sleeve 36; the cold row structure 21 is installed to the lower shell 1 2, the connecting sleeve 36 located at the top of the first cooling fan 27 is coaxially aligned with the top connecting hole 32 of the cooling tube 3. At this time, the connecting bolts can be inserted to connect the first cooling fan 27 with the cooling tube 3. When the first cooling fan 27 is raised or lowered, the cooling tube 3 is raised or lowered at the same time. The lifting plate 49 can also move between the two first cooling fans 27, and can lift up one of the first cooling fans 27 or both of the first cooling fans 27. Correspondingly, one or both cooling tubes 3 are lifted along the circular groove 31, and different cooling modes are achieved.

[0056] In one of the embodiments, a longitudinal movable hole 33 is longitudinally opened in the first cooling fan 27, and a longitudinal movable rod 28 is installed in the longitudinal movable hole 33. The bottom of the longitudinal movable rod 28 is connected to the top of the installation box 22, and the longitudinal movable rod 28 is nested with a tension spring 29 installed between the first cooling fan 27 and the installation box 22; when the heat generation is small, the heat dissipation tube 3 needs to be lowered into the circular groove 31, and the side heat dissipation hole 38 is not exposed; at this time, the lifting plate 49 is not subjected to force on the first cooling fan 27, and under the elastic action of the tension spring 29, the first cooling fan 27 will approach the installation box 22 along the longitudinal guide rail, and at the same time, the heat dissipation tube 3 descends along the circular groove 31, so that the heat dissipation tube 3 and the upper shell 11 remain flush, ensuring an integrated structure.

[0057] The wind control assembly 4 also includes a first spare seat 41 installed at the bottom of the lower shell 12, and the top of the first spare seat 41 is connected to the power supply cavity 13 in the lower shell 12; a longitudinally arranged first drive plate 42 is installed in the first spare seat 41, and the top of the first drive plate 42 extends outward and extends into the upper shell 11.

[0058] It should be noted that a first snap-on male seat is installed on the top of the first spare seat 41, and a first snap-on female seat connected to the first snap-on male seat is provided at the opening at the bottom of the lower shell 12, and the first spare seat 41 is disassembled and connected through the first snap-on male seat and the first snap-on female seat; when the height of the first cooling fan 27 needs to be automatically adjusted, the first spare seat 41 is installed on the bottom of the lower shell 12 through the first snap-on male seat and the first snap-on female seat.

[0059] Specifically, the first driving plate 42 is provided with a movable driving member for driving the lifting plate 49 to move in the vertical direction and laterally between the two first cooling fans 27; the movable driving member includes a first screw rod 43 and a second screw rod 44 which are longitudinally arranged and rotatable, and the first screw rod 43 and the second screw rod 44 are arranged in parallel and spaced apart, and the first screw rod 43 is embedded with a transmission screw sleeve 456, which is transmission-connected to the lifting plate 49. Under the transmission of the first screw rod 43, the lifting plate 49 can move in the vertical direction. After the lifting plate 49 abuts against the first cooling fan 27, it can drive the first cooling fan 27 to lift up when it is lifted or lowered, and the heat dissipation tube 3 rises along the circular groove 31. The heat accumulated in the cold row structure 21 is discharged outward through the heat dissipation holes 37 on the top of the heat dissipation tube 3 and the heat dissipation holes 38 on the side, thereby realizing multi-directional heat dissipation.

[0060] Specifically, the transmission screw sleeve 456 is connected to the transmission seat 45, and the transmission seat 45 is movably installed with a transversely arranged transmission rack 48. Under the transmission of the rotation of the first screw rod 43, the transmission seat 45 can move up and down, and the lifting plate 49 installed on the transmission seat 45 can move up and down. The transmission seat 45 is also equipped with a transmission gear 46 meshing with the transmission rack 48 and a driving gear 47 connected to the second screw rod 44. The driving gear 47 and the transmission gear 46 are coaxially connected and arranged longitudinally. The second screw rod 44 rotates to drive the driving gear 47, and the lifting plate 49 is installed on the transmission rack 48; under the transmission of the second screw rod 44, the driving gear 47 and the second screw rod 44 are driven and matched, the driving gear 47 can rotate, the transmission gear 46 rotates synchronously, and the transmission rack 48 is meshed with the transmission gear 46 at the same time. The lifting plate 49 installed on the transmission rack 48 can move horizontally, and the lifting plate 49 will move between the two first cooling fans 27; when it is necessary to lift the two first cooling fans 27, the lifting plate 49 will move horizontally and can contact the two first cooling fans 27 at the same time. Then, under the transmission of the first screw rod 43, the lifting plate 49 is lifted, and the two first cooling fans 27 are lifted at the same time. The two cooling tubes 3 are lifted along the circular groove 31, and have different cooling modes.

[0061] In this embodiment, initially, the lifting plate 49 installed on the transmission rack 48 is aligned with one of the first cooling fans 27. The lifting plate 49 performs lifting movement under the lifting drive of the transmission seat 45, and will only lift up the corresponding first cooling fan 27. When the first cooling fan 27 is lifted up, the other first cooling fan 27 will not be lifted up. When one of the cooling tubes 3 is lifted up, the corresponding heat can still be discharged. When one of the cooling tubes 3 cannot dissipate heat when lifted up, the second screw rod 44 rotates, and under the transmission action, the transmission rack 48 moves laterally to drive the lifting plate 49 to approach the other first cooling fan 27, so that the lifting plate 49 is located at the bottom between the two first cooling fans 27. When lifted up, it can resist the two first cooling fans 27, thereby driving the two first cooling fans 27 to lift up, and the two cooling tubes 3 are lifted up at the same time, increasing the heat dissipation area and improving the heat dissipation effect.

[0062] Preferably, the first spare seat 41 is provided with a first motor drivingly connected to the first screw rod 43 and a second motor drivingly connected to the second screw rod 44; the first motor and the second motor control the corresponding first screw rod 43 and second screw rod 44 respectively and independently.

[0063] Preferably, the first driving plate 42 is also provided with a longitudinal guide rod 451 along the length direction for guiding the movement of the transmission seat 45, and the transmission seat 45 is formed with a longitudinal guide hole 452 that slides with the longitudinal guide rod 451, so as to further improve the longitudinal movement stability of the transmission seat 45 and prevent lateral displacement; when the transmission rack 48 moves laterally along the transmission seat 45, the lifting plate 49 installed on the transmission rack 48 will move laterally, and it is easy to tilt due to gravity displacement; connecting bars 453 are respectively installed at both ends of the transmission rack 48, and a transverse guide rod 454 is connected between the two connecting bars 453. The transmission seat 45 is laterally penetrated with a transverse guide hole 455 for the transverse guide rod 454 to slide. When the transmission rack 48 moves, the transverse guide rod 454 will slide with the transverse guide hole 455 to ensure the lateral movement stability of the transmission rack 48.

[0064] Specifically, a temperature sensor is provided in the power cavity 13, and the temperature sensor is respectively connected to the first motor and the second motor signal. The temperature sensor is programmed by an engineer to set three temperature modes:

[0065] When the temperature is lower than the preset first temperature, the operation mode is one, and the first motor and the second motor do not work.

[0066] When the temperature is higher than the preset first-level temperature, in operation mode 2, the first motor rotates forward to drive a first cooling fan 27 and the cooling tube 3 to lift up for heat dissipation; when the temperature is lower than the preset first-level temperature, the first motor reverses and the lifting plate 49 returns to the initial position.

[0067] When the temperature rises above the preset second-level temperature, in the first step, the first motor reverses and the lifting plate 49 returns to the initial position; in the second step, the second motor first rotates forward so that the lifting plate 49 can simultaneously support the two first cooling fans 27, and then the first motor rotates forward to drive the two first cooling fans 27 and the heat dissipation tube 3 to lift up for heat dissipation; until the temperature is lower than the preset first-level temperature, the first motor reverses, and the lifting plate 49 returns to the initial height position, and then the second motor reverses and the lifting plate 49 returns to the initial horizontal position.

[0070] Furthermore, according to the heat dissipation requirements, radiator structures 21 of different specifications, such as four copper tubes, six copper tubes, and eight copper tubes, can be installed to achieve modular installation.

[0071] It should be noted that an inner magnetic block is installed at the inner end of the sliding groove 52 of the guide bar 51, and an outer magnetic block magnetically connected to the inner magnetic block is installed at the inner end of the fixed bar 54. After the radiator structure 21 is slidably installed in the lower shell 12, it is considered to be installed in place until the outer magnetic block is magnetically connected to the inner magnetic block.

[0072] It should be noted that the first joint 25 and the second joint 26 are both quick-release sealing joints, and the water-cooling pipe installed on the water-cooling head 19 can be detachably connected to the quick-release sealing joints; when the radiator structure 21 is installed in place, the installation opening 50 located on the rear end face of the lower shell 12 can open the shielding cover, and the two water-cooling pipes are respectively connected to the quick-release sealing joints, so that the water-cooling liquid of the water-cooling head 19 can cooperate with the radiator structure 21 to dissipate heat.

[0073] It should be noted that, in order to prevent leakage, opening and closing valves are respectively installed at the first joint 25 and the second joint 26, and a valve is installed at the end of the water-cooling pipe. When the radiator structure 21 is not connected to the water-cooling head 19, the valve is closed to prevent leakage of the cooling liquid. After the radiator structure 21 is connected to the water-cooling head 19 through the first joint 25, the second joint 26 and the water-cooling pipe, the valve is opened, and the cooling liquid can circulate between the radiator structure 21 and the water-cooling head 19.

[0074] The rectifier module 14 also includes an output port 61 and a mounting plate 60 for mounting the output port 61. The mounting plate 60 is mounted on the upper shell 11 via a rotating shaft 69. The mounting plate 60 can adjust the angle of the output port 61 by longitudinal rotation. A side mounting port 62 for mounting the output port 61 is formed on the side of the lower shell 12. An upper mounting port 63 for mounting the output port 61 is formed on the top of the upper shell 11. The mounting plate 60 can adjust the angle of the output port 61 by longitudinal rotation so that the output port 61 can switch between the side mounting port 62 and the upper mounting port 63. For different usage scenarios, the output port 61 is placed on the top or side to increase the usage scenarios and further improve practicality.

[0075] Preferably, the lower shell 12 is formed with a rotation hole 691 for installing the rotation shaft 69.

[0076] Specifically, the power supply body 1 is also provided with an adjustment mechanism 6 for adjusting the angle of the mounting plate 60, the adjustment mechanism 6 includes a second drive plate 64 arranged longitudinally, a second spare seat 65 is installed at the bottom of the lower shell 12, the second drive plate 64 is installed on the second spare seat 65, the top of the second drive plate 64 extends upward, and after the second spare seat 65 is installed to the bottom of the lower shell 12, the upper half of the second drive plate 64 is located in the lower shell 12.

[0077] It should be noted that the second spare seat 65 is detachably connected to the lower shell 12 using a snap-fit ​​structure similar to the first spare seat 41 . When the angle of the output port 61 needs to be automatically adjusted, the second spare seat 65 is installed on the bottom of the lower shell 12 through the snap-fit ​​structure.

[0078] The second driving plate 64 is equipped with a rotatable main gear 66 and a sub-gear 67 meshing with the main gear 66, and the sub-gear 67 rotationally drives the main gear 66 to rotate; the main gear 66 is installed with an adjusting rod 68, and the adjusting rod 68 is connected to the mounting plate 60. The second driving plate 64 is fixedly installed with a main shaft sleeve 692, and the main gear 66 is nested in the main shaft sleeve 692. The second driving plate 64 is provided with a sleeve hole 693 for installing the main shaft sleeve 692, and the main gear 66 can rotate around the main shaft sleeve 692.

[0079] Preferably, the adjusting rod 68 is installed with a threaded rod, and the threaded rod can move along the axial direction of the adjusting rod 68. When the second spare seat 65 is installed to the lower shell 12, the threaded rod is rotated so that the threaded rod is inserted into the mounting disk 60 and is movably connected with the mounting disk 60. When the main gear 66 rotates, the mounting disk 60 swings accordingly around the rotating shaft 69, which can prevent the adjusting rod 68 from breaking.

[0080] Specifically, when the second drive plate 64 is installed in the upper shell 11, the rotating shaft 69 can be dragged to align the sleeve hole 693 of the second drive plate 64 with the rotating hole 691 coaxially, and then the rotating shaft 69 is inserted into the sleeve hole 693 of the second drive plate 64 and connected to the main shaft sleeve 692, and the rotating shaft 69 is connected to the main gear 66, so that the main gear 66 can rotate around the rotating shaft 69 through the main shaft sleeve 692, and the mounting plate 60 with the output port 61 is swung at the same angle, so that the output port 61 can be switched between the side mounting port 62 and the upper mounting port 63.

[0081] The secondary gear 67 rotationally drives the main gear 66 to rotate on the second driving plate 64, and the adjustment rod 68 installed on the main gear 66 rotates synchronously, clockwise or counterclockwise, driving the mounting plate 60 to rotate longitudinally. The output module installed on the mounting plate 60 can swing the angle and switch between the side mounting port 62 and the upper mounting port 63 according to needs.

[0082] For further information, please refer to the attached Figure 8-9 The second driving plate 64 is also provided with a signal output assembly 71 which is transmission-connected with the adjusting rod 68. The signal output assembly 71 comprises a first guide cylinder 71 which is arranged longitudinally. The first guide cylinder 71 is formed with a first vertical guide hole 78 and a second vertical guide hole 79. The first vertical guide hole 78 is slidably mounted with a first vertical rod 76. The second vertical guide hole 79 is mounted with a second vertical rod 77. The top of the first vertical rod 76 is movably connected with a first transverse rod 74. The top of the second vertical rod 77 is movably connected with a second transverse rod 75. The first transverse rod 74 and the second transverse rod 75 are both radially arranged along the main gear 66. The main gear 66 is mounted with a fixed sleeve 73. The first transverse rod 74 and the second transverse rod 75 are both connected with the fixed sleeve 73. The adjusting rod 68 is mounted on the fixed sleeve 73.

[0083] In this embodiment, when the main gear 66 rotates, the first transverse rod 74 swings continuously, and the angle between the first transverse rod 74 and the first vertical rod 76 changes. At the same time, the angle between the second transverse rod 75 and the second vertical rod 77 changes. At the same time, the first vertical rod 76 will be guided and moved along the first vertical guide hole 78, and the second vertical rod 77 will be guided and moved along the second vertical guide hole 79. When the adjustment rod 68 swings, the guide structure moves adaptively to ensure that the output port 61 can switch between the side mounting port 62 and the upper mounting port 63.

[0084] Furthermore, the second driving plate 64 is installed with a third driving motor, and the third driving motor is drivingly connected to the sub-gear 67 , and the sub-gear 67 is driven by the third driving motor to rotate, thereby realizing the rotation of the main gear 66 .

[0085] A second guide cylinder 72 is installed at the bottom of the first guide cylinder 71, and a first contact 81 and a second contact 82 are installed at the top of the second guide cylinder 72, wherein the first contact 81 is coaxially aligned with the first vertical guide hole 78, and the second contact 82 is coaxially aligned with the second vertical guide hole 79; the length of the first transverse rod 74 is greater than the length of the second transverse rod 75, and the length of the first vertical rod 76 is greater than the length of the second vertical rod 77; when the adjusting rod 68 is located at the three o'clock direction of the main gear 66, the bottom of the second vertical rod 77 contacts the second contact 82, and when the adjusting rod 68 is located at the twelve o'clock direction of the main gear 66, the bottom of the first vertical rod 76 contacts the first contact 81.

[0086] In this embodiment, when the adjustment rod 68 is located at the three o'clock direction of the main gear 66, that is, the output port 61 is located at the side mounting port 62, the first horizontal rod 74 and the first vertical rod 76 are perpendicular. Since the first vertical rod 76 is located on the left side of the second vertical rod 77 and the top of the first vertical rod 76 is higher than the top of the second vertical rod 77, the bottom of the second vertical rod 77 will extend downward to contact the second contact 82.

[0087] In this embodiment, when the adjustment rod 68 is located at the twelve o'clock direction of the main gear 66, that is, the output port 61 is located at the upper mounting port 63, the first horizontal rod 74 and the first vertical rod 76 are vertically aligned, and the tops of the first vertical rod 76 and the second vertical rod 77 are aligned. Since the length of the first vertical rod 76 is greater than that of the first vertical rod 76, the bottom of the first vertical rod 76 will extend downward and contact the first contact 81.

[0088] The first contact 81 and the second contact 82 are both installed with sensors, and the sensors are connected to the third drive motor signal. The power supply body 1 is installed with a first control button and a second control button, and the first control button and the second control button are both connected to the third drive motor signal.

[0089] When the output port 61 needs to be rotated to the upper mounting port 63, the first control button is pressed, the third drive motor reverses, the main gear 66 rotates counterclockwise, and the adjustment rod 68 swings to the twelve o'clock position of the main gear 66 until the bottom of the first vertical rod 76 extends downward and contacts the first contact 81. At this time, the sensor of the first contact 81 outputs a pulse signal to the third drive motor, and the third drive motor stops rotating, so that the output port 61 remains at the upper mounting port 63.

[0090] When the output port 61 needs to be rotated to the side mounting port 62, press the second control button, the third drive motor rotates forward, the main gear 66 rotates clockwise, and the adjustment rod 68 swings to the three o'clock position of the main gear 66 until the first horizontal rod 74 and the first vertical rod 76 are vertical. The bottom of the second vertical rod 77 will extend downward and contact the second contact 82. At this time, the sensor of the second contact 82 outputs a pulse signal to the third drive motor, and the third drive motor stops rotating, so that the output port 61 remains at the side mounting port 62.

[0091] It should be noted that the first driving board 42 and the second driving board 64 will not occupy much space in the power cavity 13 , and will not affect the circuit layout of the rectifier module 14 , thus ensuring the normal operation of the switching power supply.
